unable to add property package to steady-state simulation

[András Károly Hevesi]

Hi Daniel!

I've been experiencing a problem, when I try to add a PP to my steady-state simulation.

DWsim v8.6.1.

Caught unhandeld exception: The type initializer for 'Newtonsoft.Json.Json Writer' threw an exception

System.TypeInitializationException: The type initializer for 'Newtonsoft.Json.JsonWriter' threw an exception. ---> System.IO.FileNotFoundException: Could not load file or assembly 'System.Runtime.Serialization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies.

Thank you in advance.
